Abstract

The invention discloses a method of t-butanol catalytic oxidation, which is characterized in that t-butanol, solvent, oxygen, hydrogen and diluent gas at a mole ratio of 1:(0-80):(0.2-20):(0.1-10):(0-100) react in the presence of a catalyst under 0.1-3.0MPa<1> at 0-180 DEG C. The catalyst is a microporous titanium-silicon material or a compound containing the microporous titanium-silicon material. The composition of the microporous titanium-silicon material is expressed as xTiO2*100SiO2*yEmOn*zE with an oxide form, wherein x ranges from 0.001 to 50.0; the sum of y plus z ranges from 0.005 to 20.0; the ratio of y to z is smaller than 1; E is one or more metal noble metals selected from Ru, Rh, Pd, Re, Os, Ir, P and Au; m and n are numbers required for meeting the oxidation state of E; and material grains are partially or totally hollow-structured. The method has the advantages of high t-butyl hydroperoxide selectivity and good product activity stability, and facilitates industrial production and application.

Description

technical field [0001] The invention relates to a method for oxidizing tert-butanol, and more particularly relates to a method for catalytically oxidizing tert-butanol with a microporous titanium-silicon material containing precious metals as a catalyst. Background technique [0002] Tert-butyl hydroperoxide, also known as tert-butyl peroxide (English name Tert-butyl HydrogenPeroxide, abbreviation: TBHP), is widely used in vinyl monomer polymerization and copolymerization initiators, adding sulfur to natural raw rubber, and improving diesel fuel Cetane number, tert-butyl peroxide group introducing agent, can also be used as crosslinking agent for unsaturated polyester at medium and high temperature. [0003] Today, industrial production of tert-butyl hydroperoxide is mainly obtained by catalytic oxidation of tert-butyl alcohol with sulfuric acid as catalyst and hydrogen peroxide as oxidant. This method has equipment corrosion and harmful emission, which is extremely inconsi...
